Is it, or isn't it?

8:05 AM EST 11/9/11 As reported by Forecaster Jason in our Tropical Zone page on facebook, the 2 PM Tuesday advisory from the National Hurricane Center has redesignated once "Sub-Tropical Storm Sean" into a full tropical system. Since forming earlier today, Sean has transitioned from a subtropical cyclone to one with tropical characteristics, including increased deep convection as shown by  the "clouds blobs" in the right front quadrant. View the latest NOAA visible and enhanced satellite imagery loops. 

Although near-shore Tropical Storm Warnings are in effect along the Carolina and Virginia coast, primary hazards will be to shipping and cruiseline lanes. For now, Sean ISN'T expected to impact the U.S., save for some rip currents to develop along the Carolina coast in the next 24-48 hours. Maximum sustained winds are still at 45 mph with minimum central pressure of 1002 mb. This storm may strengthen slightly over the next couple days, and as a precaution, the government of Bermuda has hoisted a Tropical Storm Watch for the island. 

Now for something completely different...yet similar. 

Meet "Rolf" the hybrid tropical cyclone.  

We direct you to this link by Dr. Jeff Masters of The Weather Underground for a thought-provoking report on a cyclone which ALSO developed tropical characteristics...in the Mediterranean Sea! Though not a common occurrence due to overall sea surface temperatures below 80 F, tropical storms have formed in the Mediterranean. It IS presenting the classic spiraling signature of a developing cyclone. NOAA's Satellite and Information Service (NESDIS) and the U.S. Navy have designated it 99L and have classified it as a tropical disturbance, based on wind estimates of 40-45 mph. (Forecasters Jason M. and Mr. Foot)
